Question

if 20 mL `(M)/(10)Ba(MnO_(4))_(2)` compeletely reacts with `FeC_(2)O_(4)` in acidic medium,
Q. m" Eq of "`FeC_(2)O_(4)` reacted is
A. 6
B. 20
C. 40
D. none

Answer 1

Correct Answer - B
`10e^(-)+undersetunderset(2x=14)(2x-16=-2)(2MnO_(4)^(ɵ))tounderset(2x=4)(2overset(+2)(Mn))]n=10`
`FeC_(2)O_(4)(n=3)`
`(Fe^(2+)toFe^(2+)+e^(-), and C_(2)O_(4)^(2-)to2CO_(2)+2e^(-))`
`FeC_(2)O_(4)-=Ba^(2+)(MnO_(4)^(-1))_(2)-=CO_(2)`
`C_(2)O_(4)^(2-)-=(MnO_(4)^(-2))_(2)-=CO_(2)-=20xx(1)/(10)xx10`
